Quick Start

Using vim-plug:

Plug 'autozimu/LanguageClient-neovim', {'do': './install.sh' }

" (Optional) Multi-entry selection UI.
Plug 'junegunn/fzf'

" (Completion plugin option 1)
Plug 'roxma/nvim-completion-manager'
" (Completion plugin option 2)
Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

Example configuration

" Required for operations modifying multiple buffers like rename.
set hidden

let g:LanguageClient_serverCommands = {
    \ 'rust': ['rustup', 'run', 'nightly', 'rls'],
    \ 'javascript': ['javascript-typescript-stdio'],
    \ }

nnoremap <silent> K :call LanguageClient_textDocument_hover()<CR>
nnoremap <silent> gd :call LanguageClient_textDocument_definition()<CR>
nnoremap <silent> <F2> :call LanguageClient_textDocument_rename()<CR>

Run command nvim +PlugInstall +UpdateRemotePlugins +qa in shell to install this plugin. Install corresponding language servers. Restart neovim/vim and language services will be available right away. Happy hacking!
